Hey, sorry to hear you’re having trouble with sending emails through Outlook on your Android device. The error you’re seeing, with the codes “120” and “e566,” usually points to a connection issue or authentication problem. Here are some steps to help you troubleshoot and fix this issue:

  1. Check your internet connection: Ensure you have a stable internet connection. A weak or unreliable connection might be causing the problem.

  2. Update your Outlook app: Make sure your Outlook app is updated to the latest version. Sometimes, updates can resolve issues like this. Go to the Google Play Store, search for Outlook, and update if necessary.

  3. Verify your account login: Double-check your email login credentials. If you’ve recently changed your password, ensure it’s updated in the Outlook app. Go to Outlook > Settings > Accounts > Edit. Enter your password, and tap “Save” to refresh the connection.

  4. Reset your account settings: Sometimes, setting your account to “manual” can help. Here’s how:

    a. Go to Outlook > Settings > Accounts > Edit.
    b. Tap “Advanced” and then change the “Server” setting to “Manual”.
    c. In the “Server” field, enter “smtp.office365.com” (if you use a personal account) or your company’s SMTP server (if you use a work account).
    d. Set the “Port” to 587 and ensure “Use SSL/TLS” is on.
    e. Save and then log back into your account.

  5. Clear cache and data: Sometimes, clearing the app cache and data can resolve issues. Go to your Android device’s Settings > Apps > Outlook > Storage > Clear Cache and Clear Data. Then, reopen Outlook and log back into your account.

  6. Check if your email provider has issues: There might be an issue on the server side. You can check the status of your email provider’s services, like Office 365 or Gmail, to see if there are any known outages or maintenance.

  7. Uninstall and reinstall the app: If none of the above steps work, try uninstalling Outlook from your Android device and reinstall it from the Google Play Store.
